2 Claims. ((11. 36-44) This invention relates to new and useful improvements and structural refinements in medicated insoles for shoes, the principal object of the invention being to pro 'de an insole containing pockets filled with powderous medicated material which may be diffused through apertures in the upper surface of the insole to preserve the feet in a dry, comfortable condition with freedom from perspiration.

Althougn it is appreciated that medicated insoles are broadly old and well known, an important feature of the instant invention resides in the provision of resilient, porous cushions in the pockets of the insole, the pores and recesses of the cushions accommodating the powderous medicated filler and, in a sense, controlling the rate of diffusion thereof automatically in accordance with the application and removal of weight of the foot on the insole while walking.

Some of the advantages of the invention lie in its simplicity of construction, in its efficient operation and in its adaptability to economical manufacture.

With the above more important objects and features in view, and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of the invention;

Figure 2 is a transverse sectional View, taken substan tially in the plane of the line 22 in Figure 1; and

Figure 3 is a top plan view of one of the cushions used in the invention.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a medicated insole which is designated generally by the reference character it; and consists of upper and lower panels 12, 14 which are superposed and coextensive in area with each other, while a marginal seam 16 secures together the marginal edge portions of the two panels, as will be clearly understood.

A reversely curved, continuous seam 18 also connects together the panels 12, 14, the seam 18 having what for purposes of convenience may be designated as the first region 20, the second region 22 and the third region 24. The region extends from the marginal seam 16 at a point 26 adjacent the outside edge of the instep portion of the insole, toward the inside edge of the front portion of the insole where the second region 22 becomes a continuity of the first region and extends rearwardly in spaced relation to the marginal seam 16 at the inside edge of the front portion of the insole. The third region 24, which is substantially arcuate, constitutes a continuation of the second region and terminates at the marginal seam 16 at a point 28 adjacent the inside edge of the instep. The first region 20 of the seam 18 defines a relatively large pocket 30 between the panels 12, 14, while the third region 24 similarly defines a relatively small pocket 32 at the inner side of the instep portion of the insole. The second region 2%) defines a relatively narrow passage 34 between the pockets 30, 32.

The pockets 30, 32 contain cushions of resilient, porous material, such as sponge rubber, or the like, one of these 2,713,215 Patented July 19, 1955 cushions being illustrated at 36. The cushions are provided with a plurality of recesses 38 and a flexible, imperforate membrane 40 is secured by adhesive to the underside of each cushion to provide a closure for the bottom of the recesses.

The pores of the cushions, as well as the recesses 38 thereof contain powderous medicated filler 42 and the upper panel 12 of the insole is provided with a plurality of apertures 44 communicating with the pockets 30, 32 so that each time the weight of the foot is placed upon the insole, the cushions in the pockets will be somewhat depressed and the powderous medicated material will be diffused t rough the apertures into the shoe.

If desired, the cushions in the pockets may be periodicarly refilled with the medicated powder, this being achieved by inserting a suitable nozzle (not shown) through a space 46 provided in the marginal seam 16 into the passage 34, so that through the medium of this passage the nozzle may then be maneuvered so as to discharge powder under pressure into the pockets 30, 32.

it is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

l. A medicated insole having front and rear end portions and a relatively narrow instep portion therebetween and also having inner and outer side edges, said insole comprising upper and lower panels superposed on and coextensive in area with each other, a marginal seam securing together marginal edge portions of said panels, a reversely curved continuous seam having a first region extending from the marginal seam at a point adjacent the outside edge of the instep portion forwardly and inwardly toward the inside edge of the front portion, a second region extending rearwardly in spaced relation to the marginal seam at the inside edge of the front portion, and an arcuate third region terminating at the marginal seam adjacent the inside edge of the instep, the first and third regions of the reversely curved seam defining between said panels respectively a relatively large pocket in the front portion and a relatively small pocket at the inner side of the instep portion, the second region of the reversely curved seam coacting with an adjacent portion of the marginal scam in defining between said panels a relatively narrow passage connecting said pockets, said upper panel being provided with sets of apertures communicating with the pockets, and a powder containing cushion provided in the pockets for diffusing powder through said apertures.

2. The device as defined in claim 1 wherein said cushion is provided with a plurality of relatively large recesses having medicated powder therein.
